Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed April 241. 1907. Serial No. 369,961.

To all whom it may concern: l

Be it known that I, FRANK DE CoLfoNY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Power-Transmitters, ol.which the following, is a specification.J l

My invention relates to an improvement in the class of power transmitters, in which thedriving and driven wheels form, between them, intercommunicating chambers for oil serving as the power-transmitting nledium between abutments on the respective wheels for transmitting the rotary motion of one to the other.

The primary object of my invention is to provide a novel and simple construction'ofpowentransmitter involving the principle ol operation 'relerredto In the accompanying drawings, Figure 1 is a broken view showing my improvedi transmitter in .sectional elevation, the section being taken at the irregularlinel 1-7-1 on Fig. 2 and viewed in the direction of the arrows; and Fig. 2 is a section taken at the line 2 of Fig.

` 1 and viewed in the direction of the arrow, showing the transmitting mechanism mainly in elevation, with the -containing a stufi'ng-box 12.

separable side of the outer wheel removed. f

On the ydrive-shaft 3 is mounted` to rotate with it, a hollow" drive-wheel 4 consisting ol' a side v5 having a sleeve 6 and a central hub 7 alining with the sleeve, a rim. 8, and a side screwed to the rim and provided with a hub 10 and a sleeve 11 extending therefrom and Surrounding the sleeve 11, and adapted to rotate therewith, is the longitudinally shiftable sleeve 13, serving the purpose herein alter explained. A driven-shalt 14 is journaled in the hub 7, wherein it is surrounded by a bearing 15, prelerably of Babbitt metal, and extends loosely through the hub l0 and thrfnlglrthe stufling-box inthe sleeve l l. with the shaft, a wheel 17 having a nel) 18 and a peripheral rim ,19 fitting closely between the sides ol the drive-wheel, with which it is concentric. Within the wheel 4, bet een the rims 8 and 19, is' an annular partition 20 litting between and let into the sides ol' the drive-wheel, to which it is'securcly fastened by screws 2l. The annular partition divides the space between the driving and driven wheels into 'an outer chamber 22 and an .inner chamber 23, this partition extendingI circumerentially from a point 24 to a point 25, between which points it fprrns the opening 26 to afford open communication between the two chambers for the circulation of the liquid, preferably oil operating'in the manner hereinafter described. Adjacent tothe opening 26 is formed in the partition 20 a port 27 flanked by guide-recesses 28, 28 extending transversely ol the partition for reciprocably confining guide-flanges 29, 29, extending from ,a slide valve 30, adapted to regulate the extent of opening and closing theport 27. A stem 31 extends from the valve 30 through a stuffing the sleeve 13, and a fork` 42 in Vwhich'the lever On'tbe shalt 14, is secured at its hub 16 to rotate j box 32 in the wheelsaide 9, beyond which its outer end is connected with .the adjacent end of a lever 33 provided on its opposite end with a yoke 34 straddling and pivotally connected at 35 with the sleeve 13, and iul- /crumed between its ends on a bearing 36 projecting from the head 9.

For shiltingthe sleeve 13 to move the valve 30,4 an

operating lever 37 is provided, suitably fulcrumed at 38 on a stationary bearing 39 and connected with the sleeve'in a manner to permit rotation thereof. The connection shown consists oi a yoke 40 straddling acircumi'erential groove 41 formed about the outer end oi 37 terminates, straddling the yoke 40 and connected at its lower ends therewith* by pivot-pins 43. u

At the opening 26 is pivotally supported at o'ne end in` the adjacent end 24 -of the partition 20, an abutment 44, containing a passage 44, the abutment fitting snugly but movably between the inner surfaces of the sid es of the drivewheel and yieldingly held at its free end in contact with the rim 19 o the driven-wheel, by a spring 45 fastened to the adjacent guide-bearing for the valve 30. At diametrically opposite points in' the wheel 17 are formed, through its rim 19 and extending into the `web 18, the recesses 46, 47. 1n the recess 46 is pivoted atV one end an abutment 48, to work at its'free end against a metal wearing plate 49, let into the recess, in which is secured a spring. for yicldingly holding the abutment in bearing contact at its free end with the inner surface of the partition 20; the abutment fitting endwise snugly but movably between the wheel-sides-5 and 9. A similar abutment 51 is pivotally supported in the same way in the recess 47, and is pressed by a spring 52; this recess being also equipped with a wearing plato 53 for the free end ol thc abutment.

To the opposite inner surfaces ol' the sides 5 and 9 ol the drive-wheel are fastened to extend betwcon the points 54 and 55 in the chamber 23 similar crescentshaped caxn-plates 5G, 5G, lor the purpose hereinafter explained; and for a purpose supplementing that of these can1s,'tl1e rini 19 of thc driven-wheel has provided upon it, adjacent to the free ends of the abutments 48 and 51, thc similar cani-surlaces 57, 5 8.

The operation is as follows: With the chambers 22 and 23 lilled with oil, as the preferred liquid for the purpose, and which is free to llow in both chambers the oil confined between thc abutmcnts 44 and 48 can-y not escape and forms an unyielding power-transmitting medium between them. Opening the valve, more or 1ess\,\by manipulating the lever 37 to shift the sleeve 13 proport vnate and the eby lever S3 on its lffulcrum, permits a quantity of the voil between the abut- ,ments Mandfl 'to escape into the chamber 22, with the orlslssiiil y'aioutnne `15.4 rid lforcing it inward. Thus a space is result that, j the continued rotation of the .drive-wheel att esame speed the abutment-ifi travels with more hereby riding the cams 56 upon the producedjbejtween the .cams andthe edge'oi the abutmentcoritacting therewith, through which the oil ahead of the-abutment may pass. In this way the speed of theQdriven-wheelis reduced relative to that of the drivling-wheel. .siW-ill be understood, until the cams 56 have riddenover the abutment 48 sufficiently arto;

the abutment 51 will oppose the abutment 44 ;vwhile th e abutment. will alone oppose the abutment 44 when the abutment 48 is wholly Within its recess. vflnasmuch at enough to .avdia obstructing the abutment .44 when it meetsthe same', the cam surfaces 57, 58 are provided to ride the abutment 44 over them. It will furthermore beunderst'od that maintaining the valve open toany given extent, maintains the same relative 'reduction of speejd of the driven wheel, while the relatively greater speed of rotationfof the drivingwheelcauses the cams.
